Can someone tell me the true cost of getting Sky HD to my requirements. My needs are as follows: 1. I have a normal Sky Box (not Sky +) in my living room at the moment with the basic £15 package. 2. I would like to replace it with a Sky HD box. 3. I do NOT want multi room, just the Sky HD box in my living room only. 4. So what would be the cost off...... 5. Box/ instalation/ NO premium chanels, just the basic £15 package. 6. Box/instalation/ two premium chanels. During my research into this I have found 3 different prices for each of 5 and 6. Can some explain the true cost?
